... Configuration management, as shown in Figure 4- 1, con sists of four basic functions3 (DOD, 1995; Buckley, 1993; Configuration management is a process to identify the Blanchard, 1986~: functional and physical characteristics of a software, firm ware, or hardware item during its life cycle; control changes to those characteristics; and record and report change pro cessing and implementation status. Configuration manage ment is applied to ensure operational efficiency and control cost and may be applied to achieve uniformity in proce dures and practices within the FAA and between the FAA and industry.

... As suggested above, the control function of configuration management is to subject all changes to a CI to review and approval by authorized personnel. Configuration status accounting and auditing are tasks that must be diligently performed to maintain configuration control.

... Several software-based configuration management tools are available to aid in the control task of a configuration management plan, some of which facilitate automated control of CIs. Configuration-Management Tools4 There are a variety of software tools that are useful for establishing and maintaining a configuration management plan.

... A1though other types of testing may be undertaken by the FAA, manufacturers, or end users, the seven listed above are the TABLE 4-1 Seven Proposed Testing Levels during the Life Cycle of an EDS Test Level Purpose Location Test Objects Frequency Precertification Determine if technology is ready for certification testing. Manufacturer's site Test articles Oncea Qualification Verify the performance of an individual manufactured Manufacturer's site Secondary standard Oncea unit to qualify that unit for deployment.

... at the FAA Technical Center using a bag set that is entirely different from the bag set used for certification testing. In addition, Recertification testing typically includes operational testing at airports using actual passenger baggage (without explosives or simulants)

... For example, equipment using image data for classification of objects may be partially evaluated through the measure of parameters such as contrast sensitivity, system spatial resolution, and the quantity and character of noise and related parameters (ICRU, 1995~. This International Commission on Radiation Units and Measurements report describes a means of evaluating the random fluctuations due to the statistical processes by characterizing the manner in which the noise power is distributed over spatial frequency.

... Each one is tailored to meet the specific needs of a particular organization. The panel considered the following quality standards from government sources and commercial industry for the FAA to use in developing its framework for a quality management program: 1 ~7 · U.S.

... Discussion of FAA Type Certification and the FDA's Good Manufacturing Practices can be found in Appendix D ISO 9000 Series Quality Standards The ISO 9000 series international standard specifies quality system requirements for use when a supplier' s capability to design and supply products that meet a designated standard needs to be demonstrated (ISO, 1994~.

... Part of the ISO 9000 series quality standards is a set of guidance documents that can be used to help interpret and tailor the requirements of the standards to a specific business (ISO, 1994~: 1.
